Our study showed that PTK7 protein showed abnormally high expression mainly on the cell cytoplasm of cervical cancer cells, and this was different from a previous study by Chen et al. which was shown that PTK7, as a target membrane receptor, expression was different on the cell membrane of HeLa cervical cancer cells in comparison with human leukemia CCRF-CEM cells [32]. The gene discussed is PTK7; the disease is leukemia.
